To all whom it may concern: I

Be it known that I Wrnm'an D. James, a citizen of the United tates,residing at Fort Atkinson, county of Jefl'erson,"and State of Wisconsin,have invented new and useful Improvements in Carriers, of'which thefollowing is a specification.

My invention relates to improvements in that class of carriers which aremovably suspended from a track and the receptacle is adapted to be lowepreparatory to being filled, and when filled, is raised pre ratory tobeing moved along the track to t e lace where its contents are deosited, an the same pertains more especia ly, among other things,--1st,to the device for lockingand retaining the litter receptacle at anydesired oint of adjustment between the ground and the supporting track;and 2nd, to the brake mechanism by which the movement of the receptacleis retarded as it is being lowered.

My invention is further explained by refcrcnce to the accompanyingdrawings, in which- Figure 1 represents a side view, and Fig. 2 an endview of my carrier as it appears when suspended from a track. Fig. 8represcnts an enlarged end view, and 'Fig. 4 a side view of the u erportion of the carrier, showing the loc ng mechanism for so porting thelitter rece tacle and the friction brake b which e downward movenicnt ofsuc receptacle is retarded after the locking mechanism has beenreleased, broken away to ctter show the construction. Fig. 5 represeatsa side view of the brake wheel and locking mechanism by which themovement of the rece tacle is controlled, said view up rcsentin t eopposite side from that shown in Fig. and ig. 6 re resents a top view ofthe device shown in ig. 5, in connection with the supporting shaft andsprocket wheel by which motion is communicated to said an )portingshaft.

like parts are identified by the same reicrcncc numerals throughout theseveral views.

1 represents the litter rece tacle which is suspended from a wmdings aft2 through the chain 8, pulleys 4, 4, an rs 5, 5, and

ivotal bolts 6, 6, by whic bolts said iangers are pivotall connectedwlththe respective ends of sai receptacle. The chain 3 is connected atits respective ends with the swiveled blocks 7 through the hooks 8, whenit passes from thence down and beneath the pulleys 4, thence up andaround the shaft 2, and is then connected near its center to the centerof the shaft. 2 by the clamping member 9. The swivcled blocks 7 arerespectively connected with the track 10 by the ban ers 11, and pulleys1Q.

13 is an enc lless operating chain. Motion is communicated from theendless chain 13 t0 the shaft 2 throu h the brake wheel 1-1, shaft 15,sprocket w eel 16, sprocket chain 17, and sprocket wheel 18. saidcndlcss chain 18 being moved in one direction when raising thereceptacle 1, and in the opposite direction as said receptacle islowered of its own ravity.

The evice thus far described is subsiantiall of ordinary construction,and invention erein is redicated moreespecially- 1st, 11 on the bra emechanism for retarding the ownward movement of the receptacle when thesame is released from the clutch mechanism, and 2nd, upon the device forretaining the receptacle 1, together with its load, either in itselevated position, or at any intermediate point between its extremeupper and lower positions, consisting in the operating lever 19, brakemember 20, clamping lever 21, means for pivotally supportin said lever19 eccentric to the brake W eel 14, means for ri idly securing the brakemember .20 to said ever 19, and means for pivotally connecting the clam)ing lever to said operatin lever 19, where v, as the free end of Sfll(lever 19 is moved downwardly, the clutch lugs on said clamping lever 21are disengaged from the rim 2?) of the brake wheel 14. when the brakemember is brought firmly against the inner opposing surface 23 of said\vhccl. whcrcby the revoluble movement of said wheel and the downwardmovement of the receptacle 1 are retarded, and whereby the receptacle 1is permitted to move downwardly more or less rapidly accordin to thepressure upon the free end of said Fever 19. When, however the free endof the lever 19 is released from the hand of the operator, the oppositeend 24 of said lever is permitted to move downwardly of its own gravity,whereby the rim 25 of said wheel 14 is clutched be.- tween the opposinglugs 26 and 27, and whereby the revolving, movement of said wheel 14 isstopped the instant the lever T t BED! AVAILABLE COP inanaesthesiamagnes umo ious" that by "the" sa'me" do\vnward movement ofthe free end of said operating leverwhlch with the inner surface of saidfiange'an'd thereby simultaneously retards the revoluble movement ofsaid 'wheel l4 and the downward movement of thereceptacle.

While my invention is adapted to be used as a litter carrier, itwill. beunderstood that.

the same is equally adapted to be used for handling iron,.coal.'-'stone, and a great variety of other materials.

Having thus described my invention, what I claim as new, anddesire tosecure by Letters Patent, is-

1. In a litter carrier, a device for sto ping the movement of the litterreceptac e when loaded, consistin in the combination of a brake wheelprovided with a projecting flange, means for manually revolving saidwheel, means for oommunicati a revolnble movement from said brake w eelto a windin shaft from which said receptacle is snspen ed, an operatinlever, means for pivotally supporting sai operating lever eccentricallyto said brake w eel, a clamping lever pivotally connected atone end tosaid operating lever and rovided at its opposite end with a pair 0gripping lugs, Silld lu s being1 adapted to grip t e respective si es oft e flange of said wheel and thereby stop the revoluble movement of isreleased from the hand of tie operator.

2... In a litter carrier, a device for retarding'and stopping themovement of the litter rece tacle when loaded, consisting in the 'u.projecting flange, means for manually "revolving said Wheel, means forcommunieatinga revoluble movement from said brake wheel to a windingshaft from which said receptacle is suspended, an operating lever, meansfor pivotally supporting said operating lever eccentrically to saidbrake w eel, a clamping lever pivotally connected atone end to saioperatin lever and provided at its opposite end wit a pair of grippinglugs, said lugs being adapted to grip the respective sides of the flangeof said Wheel, and a brake member connected with said 0 crating lever,said brake member being a opted to be brought into contact with saidbrake wheel as said gripping lugs are released from engagement with saidlaterally projecting flan e, whereby as said wheel is released from saigripping lugs, the downward movement of said receptacle will beretarded.

In testimony whereof I allix my signature in the presence of twowitnesses.
